What is changed when a pat is on PV? - Answers-Change
the set pressure increased or decreased to adjust Vt
What equation is used to reduce PaCo2 on a pat vented
with VC ventilation when the rate is needing to be
changed due to volume being high enough? - Answers-
Desired F= known F X PaCo2/desired PaCo2
What is the equation to find desired Vt in VC ventilation? -
Answers-Desired Vt= known Paco2 X Known Vt/desired
PaCo2
What is increased to increase Vt with a PVC time cycled
ventilation? - Answers-With pressure control ventilation
PCV the set pressure is generally increased to obtain the
targeted Vt. PCV is Time cycled If It is short increasing it
will increase volume delivery without increasing pressure.
